I’m printing with Basf Ultrafuse PP GF30 filament and I’m having issues with it warping. The problem is I get a perfect first layer and everything sticks fine. I come back an hour later and everything is still going perfectly but a little after two hours it starts to warp. I want to say its not a first layer issue but im not completely sure. As a test I’ve been printing a 3"x4"x.25" square with rounded corners. My settings for the best prints so far is a 247c nozzle temp, 28c bed temp with pp tape, 40mm/s speed, 91% flow, 50% fan speed, and .15mm layer heights. I’m using a .4mm nozzle and have calibrated the z offset to make pretty nice first layers. I have tested bed temps of 28c, 30c, 35c, 40c, 70c, 85c, and 90c. I have tested nozzle temperatures from 230c-280c in increments of 5. I did a flow cube calibration test which is where I got the 91% flow from. Finally I have tested fan speeds of 0%, 25% and 50%. I know PP filament is pretty hard to print but is it impossible to have no warping. Should I boost the fan speed way, slow down the print speed, increase layer height? I’m kind of running out of ideas to test now.
Hey man dis you ever solve this? Im trying to print some 3dxtech ppgf30 in mh p1s and its killing me. Ive basically used uo half the roll trying to calibrate and get prints to work but they lift iff after the first 10 kayers or so. The shrinking is suuuper visible in the first layer but they initally go down super well.
I have managed a single successful print, but the surface finish was insanely bad.
Im printing on a p1s with a 50c heated enclosure, straight onto a specialty pp print p surface 141 plate.
Printing at about 250º, I guess you would need an enclosure to prevent it from warping.
If it warps, it means that it cools faster than expected and then, shrinks. Estructural tension leads to warping and in order to avoid it, you need a stable-temperature printing enviroment…
Apart from having an enclosure, layer fan is usually set at a very low speed (20%) if not completely off for that type of materials.
Ensure your print settings are optimized for PPGF30.
